Alpha Centauri the closest star to our solar system which is 4.37 light years from the sun. It is composed of three stars those are Alpha Centauri A also which is called as Rigil Kentaurus, Alpha Centauri B also known as Toliman and Alpha Centauri AB known as Proxima Centauri. With unaided eye this the two component appears as a single point of light with apparent magnitude of -0.27 that makes the brightest star in southern constellation of centaurus which falls under the third brightest stars in the night sky.

Alpha Centauri A has 1.1 occasions the mass and 1.519 occasions the glow of the Sun, while Alpha Centauri B is littler and cooler, at 0.907 occasions the Sun’s mass and 0.445 occasions its iridescence.

The match circle about a typical focus with an orbital time of 79.91 years. The curved circles have a checked unusualness, so the separation between them shifts from almost that among Pluto and the Sun (35.6 cosmic units), to that among Saturn and the Sun (11.2 AU).

In spite of the fact that not unmistakable to the exposed eye, Proxima Centauri is the closest star to the Sun, at a separation of 4.24 light-years (1.30 pc). The separation between Proxima Centauri and Alpha Centauri AB is around 13,000 galactic units (0.21 ly), equal to around multiple times the sweep of Neptune’s circle. Proxima Centauri b, an Earth-sized exoplanet in the tenable zone of Proxima Centauri, was found in 2016.
